Pavement marker

Abstract

A hardened steel pavement marker having a base with raised protective cross ribs and reflectors thereon, and a depending skirt for embedment in the pavement, the skirt being scalloped and having holes therein.

We claim: 
     
       1. A raised plowable pavement marker comprising a hardened steel inverted cup-shaped member including a base and a full surrounding circular depending skirt, said skirt having means to hold the marker to a pavement with the skirt embedded,   a diametric ridge on the base rising above the base and presenting a convex edge for a plow to ride over,   first and second members each having a convex edge, rising above the base,   said first and second members being generally at right angles to said diametric ridge an being located at opposite ends of said diametric ridge respectively,   said first and second members each having a surface extending laterally on opposite sides of said diametric ridge, said surface rising from a peripheral edge portion of said inverted cup-shaped member and merging with said diametric ridge in the longitudinal direction of said ridge and forming a symetrical transverse arch rising from said base on opposite sides of said diametric ridge to a peak coinciding with the top of said diametric ridge,   said diametric ridge and said first and second members together with said base forming a pair of recesses on opposite sides of said diametric ridge, said recesses each having an open side opposite said diametric ridge between said first and second members,   said base between said first and second members on opposite sides of said diametric ridge being substantially flat,   at least one elongated reflector secured to said bases and located in one of said recesses alongside and substantially parallel with said diametric ridge,   said first and second members at the ends of said diametric ridge serving to protect the market and reflector from a snowplow traveling in a direction normal to said diametric ridge.   
     
     
       2. The marker of claim 1 wherein said reflector has an exposed surface slanting down from said ridge. 
     
     
       3. The marker of claim 1 wherein said reflector has a flat bottom surface contiguous with said base, a rear wall adjacent to said diametric ridge and of less height than said diametric ridge, a front wall of less height than said rear wall, and an exposed slanting surface facing outwardly through the open side of said recess. 
     
     
       4. The marker of claim 1, together with a pair of elongated ridges formed in said base, parallel to and spaced outwardly from said diametric ridge on opposite sides thereof respectively, sid elongated ridges extending between said first and second members and forming protective means in front of reflectors located in said recesses. 
     
     
       5. The pavement marker of claim 1 including a second elongated reflector secured to said base and located in the other of said recesses alongside and substantially parallel with said diametric ridge at the opposite side of the diametrical ridge. 
     
     
       6. The pavement marker of claim 1 wherein the means on the skirt to hold the marker in the pavement includes recesses in the skirt, said recesses extending inwardly from the edge of the skirt. 
     
     
       7. The pavement marker of claim 6 wherein said means on the skirt includes apertures therein. 
     
     
       8. The pavement marker of claim 6 wherein the convex edges merge into the base on an arc at the edge of the base. 
     
     
       9. The pavement marker of claim 1 wherein the reflector has a slanted surface.
